What are broad-spectrum insecticides?

• A. Pesticides that control many insect and/or mite species.
• B. Pesticides that only kill one species.
• C. Pesticides that only repel pests.
• D. Pesticides that degrade quickly.

Answer: (A)

Broad-spectrum insecticides are pesticides that control many insect and/or mite species, not just a single target pest. They work by affecting a common biological process or vulnerability shared by a wide range of pests, so one product can eliminate multiple problem species at once. This makes them useful when several pests are present or when rapid, broad control is needed. However, they can also harm beneficial insects and natural enemies, potentially leading to secondary pest problems or resistance if overused. They are different from narrow-spectrum products, which target specific pests with less impact on non-target organisms.
